Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If directional control primary function with secondary flow regulation
Valves primarily controlling direction fall under separate statistical category.
If imported as part of valve assembly or manifold
Partial assemblies or manifolds with valves classify as parts of 8481 valves.
If vehicle-specific hydraulic system integration
Vehicle parts headings take precedence for complete assemblies in motor vehicles.

Import Tips & Compliance
• Submit system diagrams showing priority circuit integration for classification support
• Certify materials for fluid compatibility (e.g
• phosphate ester resistance if specified)
• Watch for reclassification as manifolds (8481.90) if multiple functions integrated
